I have included the MCP23S08 GPIO driver provided in the distrubution. We are unable to initialize the driver while kernel bootup, majorly because on the data structure for MCP23S08 is not defined in platform file.


Can someone point us to the help on how to include the MCP23S08 driver? What is the structure elements we need to define in the platform file?


Thanks & Regards

we've had nothing to do with this device let alone the driver, so we really know nothing about it.


i imagine if you read the source code the answer would become obvious (linux/spi/mcp23s08.h).
